Natural dyes are generally obtained from the extracts of plant parts. Teak leaves produce natural and can be used to create ecoprinted works.This study aimed at utilizing teak as dye an ecoprinting material imprinted on silk fabrics using alum mordant. The s tate art this research is ecoprint materials a single piece fabric. purpose was get colors, products, add aesthetic economic value fabrics...

This study evaluated the color fastness and crust quality of eco-printed leather using various types mordant in natural dye mangrove extract. used 20 sheepskin crusts bark experimental employed a Completely Randomized Design (CRD) with different as treatments. The were Aluminum Sulfate (Al2(SO4)3), Calcium Carbonate (CaCO3), Citric Acid (C6H8O7), Ferrous (FeSO4). results showed that use (FeSO4)...

An ecological approach has been obtained by using natural dyes and mordant for dyeing process. Silk fabrics dyed using natural mordants: powder of sour pomegranate and sweet pomegranate and mixture them. A beautiful red color were obtained by using theses mordants. The color of dyed silk fabrics was investigated in CIE Lab L, a and b and K/S values. Finally, all dyed fabrics were tested for was...

The current commercial application of ink-jet reactive inks to cotton fabrics has been through pre-treating with pad liquor prior to printing. In This study made an effort to provide a single phase ink-jet printing process for printing cotton fabric using the novel cationic reactive dye in ink’s formulation. Cotton fabric was printed upon with the novel cationic reactive dye and commercial anio...

In the present work an evaluation was carried out on the effect dye-bath pH and mordant type on the obtained shades and fastness properties in wool dyeing with cochineal. In this way wool samples were first mordanted with four different mordants and subsequently dyed with cochineal at different levels of dye-bath pH. Colorimetric evaluations were carried out and fastness properties of the dyed ...

We report on a comparison of high-resolution numerical simulations of Lagrangian particles advected by incompressible turbulent hydro-and magne-tohydrodynamic (MHD) flows. Numerical simulations were performed with up to 1024 3 collocation points and 10 million particles in the Navier-Stokes case and 512 3 collocation points and 1 million particles in the MHD case. In the hydrodynamics case our ...
